From carpal tunnel to Wiinjuries, technology constantly finds insidious ways to cause users physical harm. Just yesterday a British man made headlines for suffering "the first Twinjury" -- 23-year-old PR man James Coleman slammed into a tree branch while jogging to work. Too absorbed with his Blackberry to notice the approaching obstruction, he ended up dazed and bruised on the sidewalk. "One minute I was running along posting a tweet, the next I was lying on my back on the pavement in agony," he said.

Coleman's jogging mishap led us to investigate more accidents generated by the ubiquitous micro-blogging service. As it turns out, there were quite a few. Now ponder: Can the agony of broken limbs and muscle problems be effectively expressed in 140 characters or less?

Health officials have voiced concern that Twitter encourages more frequent postings from its users, and that extra time in front of the computer or phone could lead to hazardous muscle pain. "It is highly likely anything that involves you constantly typing will increase your chances of getting RSI," says Kevin Fleisch, chairman of the London Repetitive Strain Injury Support Group. "Anybody repetitively moving their fingers is more likely to get it." Translation: Go outside and exercise (sans PDAs, please).

On May 27th, a car ran over Twitter user @DeirdreEileen's toe when she was busy tweeting. She wrote "almost risked my life by walking into a car and getting my toe ran over by a car cause:twittering. effect:hurt toe." And this little piggy cried "Wee! Wee! Wee!" all the way home.
Back in September of 2008, blogger John Chow posted a story about the "World's First Twitter Accident." He had met a fellow dotcom-er at a media summit and inquired about her leg cast. Turns out she had fractured her leg while walking and Twittering, proving once and for all that speed is not a factor in all Twinjuries.
In April 2009, another article in the Telegraph UK illustrated the scope of driving while Twittering: One in 10 drivers admits using Twitter, texting or updating his Facebook page while driving. One person stated: "I'm driving with my knees and peeling an orange ... probably not the safest thing to do," while another boasts: "Irresponsible Twitter driving ... woo." We can only assume that this has already resulted in a car accident; we just hope the reason we haven't heard about it isn't that the driver is now too dead to tweet.
